If you're tired of algorithms helping you find music and you're curious what other people you actually know are listening to, Monstro is a new service that uses your Twitter account to pull together mini-mixes based on the songs your friends enjoy enough to share with the world. You can "tune in" to mixes created by friends and other avid music-sharers, check out the service's music charts to discover new bands, and fall in love with music all over again.

Monstro uses your Twitter account to see what music you've been sharing recently, and then builds a mix based on those songs. You can click on any of them to listen, download them from Amazon or iTunes, stream on Spotify, or check out a music video at YouTube. The "Friends Mix" page shows you songs that your friends have shared on various social networks so you can listen in and hopefully discover something new. You can even see which other Twitter users have shared the same song.

If you're looking for something completely new, check out the Monstro Charts, which are a combination of popular artists overall, popular on Monstro, or popular on the social network or music service you prefer. With one click, you can see the songs and artists that users share the most at The Hype Machine, Spotify, Last.fm, Pandora, Soundtracking, and more.

Monstro isn't really a music player or streaming radio service, although you could use it that way. What it really does—and does very well—is introduce you to new bands that your friends are listening to, and lets you explore new music you may not have otherwise found on your own. It's completely free, and all you need is a Twitter account to sign up.
